Freight Broker vs. Direct Shipper: What the Right Customer Mix Looks Like for a Mid-Size Carrier

The average freight broker takes between 15 and 18 percent of the load value on every transaction. On a $2,500 dry van load, that is $375 to $450 that flows to the intermediary rather than to the carrier who owns the truck, pays the driver, and assumes all the operational risk. Most mid-size carriers know this number exists. Very few have calculated what it costs them across their entire annual freight volume.

For a carrier running 25 trucks and averaging 200 loaded miles per truck per day at $2.20 per mile, annual gross revenue sits around $40 million. If 75 percent of that revenue runs through brokers at an average margin of 17 percent, the freight brokerage industry is collecting approximately $5.1 million per year from that carrier's customers, money that those customers were willing to pay for transportation but that never reached the carrier moving the freight.

That is not an argument to eliminate brokers from your freight mix. Brokers provide real value in specific circumstances, and a carrier who tries to go fully direct before their operation is structured for it creates a different set of problems. The argument is that most mid-size carriers have never analyzed what their current broker-to-direct ratio is costing them, what the margin math looks like at different mix levels, and what a deliberate shift toward a better ratio would be worth financially.

That analysis is what this article builds.

What Brokers Actually Charge and Why It Varies

Before the margin math makes sense, the broker fee structure needs to be understood accurately. Industry data from multiple sources, including True Rates, ATS Logistics, and FreightWaves, shows that freight broker margins typically run between 10 and 25 percent of the total load value, with the average on standard lanes landing at 15 to 18 percent. On complex, expedited, or specialized freight, margins can reach 30 percent or higher.

The way this translates to a carrier is straightforward. If a shipper pays a broker $2,000 to move a load and the broker pays the carrier $1,700, the broker's margin is $300, or 15 percent of the shipper's payment. The carrier receives 85 cents of every dollar the shipper spent. On a direct relationship for the same lane, the carrier negotiates directly with the shipper and receives the full $2,000, less whatever administrative cost is associated with managing that relationship.

That $300 difference per load matters more at some times than others. In a strong freight market where rates run well above operating costs, the broker margin is an efficiency loss but not a survival question. In the market conditions that persisted through 2023 and 2024, where ATRI documented average operating costs at $2.26 per mile while spot rates sat at or below that level across much of the year, the broker's cut came directly out of a margin that was already near zero or negative. Carriers who ran primarily on broker freight during that period were, in many cases, paying the broker out of their own operating margin rather than from a surplus.

The Spot Market Problem That the Freight Recession Made Permanent

The freight recession exposed broker dependency as a structural vulnerability in a way that the industry had not seen so clearly since the 2008 financial crisis. What the freight recession revealed about spot market dependency is not an abstract lesson. It is documented in the carrier exit data: more than 88,000 trucking authorities were revoked in 2023, with FMCSA data showing a net contraction of nearly 10,000 motor carriers in the first half of 2024 alone. The carriers most exposed were those running the highest percentage of their loads through spot-market broker channels.

The mechanism is not complicated. Broker-sourced freight, and specifically spot market freight, is priced by the current market rate for capacity on a given lane at a given moment. When capacity is tight, spot rates rise and carriers benefit. When capacity is oversupplied, as it was for 13 consecutive quarters following the pandemic freight boom, spot rates compress below operating costs and carriers have no contractual protection. A carrier with 80 percent of its revenue coming from broker spot freight in a soft market is fully exposed to whatever rate the market will bear, with no floor.

DAT's broker-to-carrier rate data shows this concretely: from January 2019 to December 2023, the broker-to-carrier rate per mile declined approximately 13 percent while operating costs were rising significantly over the same period. A carrier whose cost structure grew while their broker-sourced revenue rate fell was being squeezed from both directions simultaneously.

Carriers with strong direct shipper relationships and contract freight portfolios experienced the same cost pressures but had a meaningful buffer. Contract rates during the worst of 2023 averaged $0.35 to $0.39 per mile above prevailing spot rates. A carrier running 60 percent contracted direct freight and 40 percent broker spot freight in a soft market was generating meaningfully higher average revenue per mile than one running the inverse ratio, with identical trucks, drivers, and operating costs.

The Margin Math at Three Different Customer Mix Scenarios

To make this concrete, here is how the numbers play out for a mid-size carrier running 30 trucks at 8,500 miles per truck per month, using conservative rate assumptions based on 2025 market conditions.

Total monthly miles: 255,000Assumed blended rate: $2.10 per mile (in line with late 2025 market averages for dry van)Gross monthly revenue at full rate: $535,500

Now apply three different broker-to-direct ratios:

Scenario A: 80% broker dependent (common among carriers who grew primarily on load boards)Of the $535,500 in monthly revenue, 80 percent, or $428,400, passes through brokers at an average margin of 16 percent. The carrier receives approximately $360,000 of that $428,400. On the remaining 20 percent, or $107,100, which runs direct, the carrier receives the full amount.Total monthly carrier revenue: $467,100.The broker layer costs this carrier $68,400 per month, or $820,800 per year.

Scenario B: 50% broker, 50% direct (a more balanced mid-size carrier mix)Of the $535,500, half passes through brokers at 16 percent margin. The carrier receives approximately $224,700 from broker freight and the full $267,750 from direct freight.Total monthly carrier revenue: $492,450.The broker layer costs $43,050 per month, or $516,600 per year.Compared to Scenario A, this carrier retains an additional $304,200 annually.

Scenario C: 30% broker, 70% direct (a well-developed direct shipper portfolio)Of the $535,500, 30 percent passes through brokers. The carrier receives approximately $134,820 from broker freight and the full $374,850 from direct freight.Total monthly carrier revenue: $509,670.The broker layer costs $25,830 per month, or $309,960 per year.Compared to Scenario A, this carrier retains an additional $510,840 annually.

These scenarios use identical trucks, identical routes, and identical rate assumptions. The only variable is the customer mix. The difference between Scenario A and Scenario C is over half a million dollars per year in retained revenue on a 30-truck fleet, without adding a single truck or increasing a single rate.

Understanding your fleet's cost per mile is the baseline that gives these scenarios real meaning. A carrier whose fixed and variable costs total $1.85 per mile is profitable at all three scenarios above, but the margin per mile at Scenario A versus Scenario C is the difference between a 12 percent operating margin and a thin one. A carrier whose costs total $2.00 per mile may be profitable at Scenario C and barely breaking even at Scenario A.

Why Most Mid-Size Carriers Are Stuck at the Wrong Mix

If direct shipper relationships are worth this much financially, the obvious question is why most mid-size carriers have not developed more of them. The answer is three parts structural and one part cultural.

The structural problem with broker dependency is that it is self-reinforcing. A carrier who runs 80 percent of their freight through brokers is spending their management attention on operational execution: dispatch, driver management, maintenance, compliance. They have no dedicated sales function, no time to develop shipper relationships, and no infrastructure for managing direct accounts with their own invoicing, credit terms, and customer service requirements. The operational machine runs on broker freight because that is what the organization is built to handle. Shifting toward direct requires building a different organizational capability alongside an existing operation, which requires time and attention that broker-dependent carriers chronically do not have.

The load board creates a false sense of freight security. A carrier who can always find a load on DAT or Truckstop has no immediate incentive to invest in the harder, slower work of building direct shipper relationships. The load board provides instant demand, even if the rate is mediocre. Direct shipper development does not produce a load this week. It produces a contract that runs for twelve months starting next quarter, at rates that reflect a relationship rather than spot market clearing prices.

The direct shipper approach requires a different sales skill set. Negotiating with a broker on rate is a transactional conversation that most carriers and dispatchers handle daily. Approaching a manufacturing plant's logistics director, understanding their freight patterns, and proposing a service arrangement that serves their operational needs requires a different kind of conversation. Most trucking operators are very good at moving freight and not particularly experienced at selling capacity on a strategic basis. That gap keeps them on the load board longer than their financials justify.

The cultural reason is that brokers are familiar and comfortable. There is genuine value in the convenience of broker freight: someone else finds the loads, handles the shipper communication, manages invoicing terms, and resolves problems when freight does not move as expected. Building a direct shipper book means taking on those functions internally, and many carriers are not certain their organization is ready to handle that shift cleanly.

When Broker Freight Is Actually the Right Answer

Before making the case for a more deliberate direct shipper strategy, it is worth being honest about the specific circumstances where broker freight is the correct choice.

Backhaul coverage is the clearest case. A carrier whose primary lane runs loaded from Chicago to Atlanta may not have a direct shipper relationship for the return leg. Broker freight on the backhaul, even at a lower rate, is better than running empty. The alternative is deadhead miles that cost the full CPM with zero revenue attached. A carrier who tries to build direct relationships in every lane they operate is spreading their sales effort so thin that none of the relationships develop properly.

Lane experimentation is a second legitimate use. A carrier considering expanding into a new geography or commodity type may use broker freight to test volume and profitability before investing in the sales effort required to build direct relationships there. Three months of broker-sourced loads on a new lane produces rate and volume data that makes direct shipper conversations more credible and better informed.

Overflow capacity is a third. Even carriers with strong direct shipper portfolios need a mechanism for absorbing volume spikes or covering capacity when drivers or trucks are unexpectedly unavailable. Broker networks provide flexible demand that can be engaged or disengaged without contractual obligation, which has real operational value for managing utilization variance.

The problem is not using brokers. The problem is defaulting to brokers for everything, including lanes and volumes where a direct relationship is achievable and financially worth the development effort.

How to Start Shifting the Mix

The carriers who successfully build direct shipper books do not typically start by cold-calling random manufacturers. They start by analyzing what they are already hauling and for whom, and then identifying which of their current broker lanes could support a direct relationship.

A broker-sourced load from a distribution center in Indianapolis to a retailer in Columbus is the same load that direct shippers book through brokers. The shipper is paying a broker to find a carrier for that lane. If that lane runs consistently, multiple times per week, the shipper has a recurring freight need that a direct carrier relationship could serve more reliably and possibly at a lower total cost than the broker arrangement, while the carrier earns more per load. That is the foundation of a direct shipper conversation.

The FreightWaves analysis of U.S. shipper data identified approximately 292,000 shippers generating consistent outbound freight. Within any given carrier's operating geography, that universe narrows to several hundred businesses with dock doors and regular freight volume. The carriers building direct portfolios are systematically working through that list, not waiting for shippers to find them.

The service pitch in that conversation is not "I am cheaper than your broker." It is "I operate in this lane consistently, I have the equipment and capacity to commit to your volume, and you will always reach someone who knows your freight when you call." That is a proposition that brokers, by the nature of their model, genuinely cannot match, because they are coordinators rather than operators.

How your carrier profile affects insurance pricing is also relevant here in a way that is often overlooked. Direct shipper relationships tend to produce more consistent, predictable freight patterns than spot market broker loads. Predictable freight patterns mean predictable driving behavior, which over time produces a safer and more documentable risk profile. That documentation has real value in insurance underwriting conversations.

The Mix Target for a Mid-Size Carrier

There is no universal right answer for the broker-to-direct ratio that works for every 20 to 50 truck carrier. The appropriate mix depends on operating geography, freight specialty, capacity utilization patterns, and whether the carrier has the organizational infrastructure to manage direct accounts properly.

What the margin math does establish clearly is that every percentage point of broker-sourced freight converted to direct revenue is worth a specific dollar figure, and that figure is large enough to justify substantial investment in the sales and account management infrastructure required to build a direct shipper book.

A carrier who dedicates one experienced account manager to direct shipper development, at a fully-loaded cost of $80,000 to $100,000 per year including benefits, and converts 10 percentage points of their freight mix from broker to direct over 18 months, will typically recover the cost of that investment several times over in the first full year of the new customer relationships. The math from the scenario analysis above makes that clear.

The carriers who take the longest to start are usually the ones who are most broker-dependent, because the cognitive bandwidth available to an operator running 80 percent broker freight is almost entirely consumed by day-to-day operations. The most common starting point is not a full strategy shift. It is a single conversation, with a single shipper on a lane that already runs consistently through a broker, asking whether they would consider a direct arrangement.

For mid-size carriers looking to build the operational and financial infrastructure that supports a direct shipper strategy, fleet services built for mid-size carriers is a starting point for understanding what support looks like at your fleet size.
